Explanation:

Only Codes 1, 2, 3, 5 and 6 are correct.

• According to the latest data published by Stockholm International Peace Research Institute (SIPRI), world military spending continued to grow in 2021, reaching an all-time high of USD 2.1 trillion despite the economic fallout of the pandemic.
• As a result of a sharp economic recovery in 2021, the global military burden—world military expenditure as a share of world Gross Domestic Product (GDP)—fell by 0.1 percentage points, from 2.3% in 2020 to 2.2% in 2021.

Top Spenders:

• The five largest spenders in 2021 were the US, China, India, the UK and Russia.
• They accounted together for 62% of expenditure and the US and China alone accounted for 52%.

Asia and Oceania

• The military spending in Asia and Oceania totaled USD586 billion in 2021.
• Spending in the region was 3.5% higher than in 2020, continuing an uninterrupted upward trend dating back to at least 1989.
• The increase in 2021 was due primarily to growth in Chinese and Indian military spending.
• Together, the two countries accounted for 63% of total military expenditure in the region in 2021.

Hence option 4th is correct.
